From the relieving officer's side, how should they respond to being snapped at during a tired colleague's handover, without escalating the conflict?

A. Respond with equal sharpness to make clear that the behaviour is unacceptable

B. Refuse to accept the handover at all until the other officer apologises

C. Say nothing and avoid the colleague entirely from that point onward, with no further communication about it

D. Recognise that the sharp tone likely reflects fatigue rather than a genuine personal grievance, respond calmly rather than matching the tone, ensure the handover information itself is still given and received accurately despite the tension, and raise the pattern with an officer if it continues rather than holding a grudge silently

A. Fatigue significantly affects mood regulation, patience, and communication — an officer who has worked beyond their permitted rest hours or had disrupted sleep is genuinely more likely to react sharply over small things, which is a known and documented effect of sleep deprivation, not just a character flaw

B. This is purely a clash of personalities with no connection to working hours or rest

C. Short tempers at handover are normal and should be accepted as part of shipboard culture with no further thought

D. Only physical tasks are affected by fatigue — mood and communication are unaffected by tiredness

A. There is no formal way to check this, so the matter should simply be dropped

B. Review their rest hours record against the STCW VIII/1 minimum requirements (at least 10 hours rest in any 24-hour period, at least 77 hours in any 7-day period, in no more than two periods) to see whether there has been a genuine, documented shortfall, not just a subjective feeling of tiredness

C. Assume the rest hours record is always accurate without any further investigation, regardless of what is observed

D. Ask the officer's opinion only, without checking any actual records
